SPBCIFICATION forming part of Letters Patent No. 328,276, dated October 13, 1885.

Application filcd February 11, 1885. Serial No. 155,580. (No model.)

.T0 all whom it may concern:

Be it known that we, JOHN BiissEMIR and GUsrAv HUMEL, both of Brooklyn, in Kings county, and State of New York, have invented a certain new and useful Improvement in Lamps, of which the following is a specification.

We Will describe a lamp embodying our improvement, and then point out the novel features in claims.

In the aceompanying drawings, Figure 1 is a side view of a lamp emloodying our improvement, a certain portion being broken away to exhibit parts which would otherwise be concealed. Fig. 2 is a sectional elevation of a wick-carrier, and Figs. 3 and 4 are views of certain parts of the wick-carrier detached.

Similar letters of reference designate corresponding parts in all the figures.

A designates the reservoir of the lamp. As here shown it is bowl-shaped, and has near the bottom a contraeted portion or neck, a. It is supported upon a base, B. The base B has near its top a contracted or neck-like portion, b, adapted to fit upon the portion a of the reservoir A, and be secured thereto by solder or otherwise. N ear its bottom the base B is provided with apertures a', through which air is supplied to the interior of an annular Wiek-tube, O.

The wick-tube O is composed of an inner wall, D, and an outer wall, E, united at their lower ends by a ring of metal, c, secured thereto by solder. This wiek-tube extends through the reservoir, and is secured near its lower end to the portion a of the reservoir by solder or otherwise in such manner as to be oil-tight. Holes d in the outer wall of the wiek-tube admit oil to a tubular wiek, F. I have shown the wiek F detached'from the wiek-tube and secured to a wick-carrier, G. This carrier is adapted to be moved up and down within the wiek-tube. It consists of a ring of metal, f, having serrations or teeth e, extending inwardly and circumferentially about the same. To the ring f is rigidly affixed a rack-bar, g.

H is a tube adapted to fit within the tubular wiek F. Near one end it is provided with a circumferential groove, h. The ring f having been placed about the wiek, the tube H is inserted within the wiek. lVhen the groove h is opposite the teeth c on the ring, the teeth enter the same or force the portions of the wiek with which they are in contact therein, ,and thus secure the wiek by a strong grip to the tube H. By this means the wiek may be raised eveuly, and all canting to one side, which is usual in tubular lamp wicks, is avoided.

I is a star-wheel of ordinary construction, adapted to engage with the rack-bar g of the wick-carrier G, through a slot, i, in the outer wall of the wiek-tube. This star-wheel is mounted upon a shaft, J, near one end thereof. The shaft J is journaled at one end in a bearing, j, upon the Wick'tube, and near the other in a bearing consistiug of a stufiing-box, K. The shaft preferably passes through a tube, L, secured at one end to the inner end of the stuffing-box K, and at the other to the Wicktube by solder or otherwise. Upon its outer end the shaft has upon it a hand-wheel, 7a. The stuffing-box K extends through an aperture in the shell of the reservoir, and is secured therein by solder or otherwise. It may be stuffed with any suitable material. It is provided with a screw-cap, as usual. The stuffing-box prevents the oil from escaping from the reservoir about the shaft J.

The wiek-tube passes through a suitable aperture in the top of the reservoir and extends for a considerable distance above the same.

M is an air-distributer, fitted about the wiektube in the usual or any suitable manner. It has upon it a chimney-gallery, Z. An annular defiector, N, also extends about the wiek-tube within the distributer. f';

O is a button or spreader provided with a shank, m, adapted to fit within the 'upper end of the tube P, which passes npward Within the inner wall of the wiek-tube. Spider-like devices o, arranged about the tube P, and having the ends thereof secured to the inner wall of the wiek-tube, maintain the tube P in a Vertical position. The bottom of the shank m of the button or spreader is open, and permits air to pass upward through the button or spreader. The air escapes through perforations 1' into the fiame.

The reservoir A may be filled with oil IOO 2. In a lamp, the combination, with the Wiek-tube O, of the wiek F, the ring f, having serrations or teeth e, the rack-bar g, and the 15 Vtube H, provided With the groove h, substantially as specified.
